摘要: An automatic focussing apparatus having a plurality of sensors the signal accumulation type includes accumulation-type sensor sections for respectively receiving light from different object areas. Each section produces, in response to first signal, which is variable accordance with an amount received thereby. The produced by each independently output processing circuit through terminal portion second signal. A control supplies substantially at same time, and monitors producing state independently. then reaches predetermined monitoring state.
